フェロシリコン is an essential deoxidizer in the steelmaking industry. In torch steel, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used as an alloying agent in steelmaking. adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of the steel, increase the magnetic permeability of the steel, and reduce the hysteresis loss of transformer 一般 スチール contains {{0}}.15%-0.35% silicon, structural steel contains 0.40%-1.75% silicon, tool steel contains 0.30%-1.80% silicon, spring steel contains 0.40%-2.80% silicon, and stainless acid-resistant steel contains Silicon 3.40% ~ 4.00%, 耐熱 スチール 含有 シリコン 1.00% ~ 3.00%, シリコン スチール 含有 シリコン 2% ~ 3% または より高い。
高シリコン フェロシリコン または ケイ質 合金 are used in the ferroalloy industry as reducing agents for the production of low-carbon ferroalloys. Ferrosilicon can be used as an inoculant for ductile iron when added to cast iron, and can prevent the formation of carbides, promote the precipitation and spheroidization of graphite, and improve the performance of cast iron。
addition, ferrosilicon powder can be used as a suspended phase in the mineral processing industry and as a coating for welding rods in the welding rod manufacturing industry; high-silicon ferrosilicon can be used in the electrical industry to prepare semiconductor pure silicon and in the chemical industry to manufacture silicone, etc.
